1 This invention relates to in the construction of Venetian blinds and has for its primary object to enable the slatsof the blind to be completely closed either in a downwardly or upwardly slanted arrangement. 4 Another important object ofthis invention is to provide a new and simplified operating means for raising and lowering the slats.

Another important object of this invention is to provide a heater appearing blind andon'e that is easier to clean and to operate by obviating the need for using conventional tapes, elevator cables and tilting mechanism. 7

These and ancillary objects and structural features of merit are attainedby this invention, the preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawings, wherein: r i 4 Figure 1 is a rear elevational View of the blind;

Figure 2 is a vertical sectional view with the slats illustrated in a raisedposition; and

Figure 3 is an exploded fragmentary perspecthe view of the means for supporting the slats.

In the accompanying drawings, the newtype of Venetian blind construction I is illustrated 1 and is attached to a window frame l2 by means of brackets l4 and i6 aflixed to the to-p l8 of the frame. The brackets are formed with depending parallel sections 20 and 22 which are provided 24 and 25. A spring-actuated roller 28 is rotatably J'ournalled between the branches 24 of each of the brackets and hubs 30 and 32 are formed on the opposing ends thereof by spaced sets of plates 34. A guide roller 36 is journalled between the branches 24 of each bracketa-nd operating cables or cords 38 and 4,0, coiledpon the hubs 30 and 32, extend overyand travelyon'the guide roller. U A plurality of vertically spaced and aligned slats 42 form the blind properand are'fsupported soiaiuisl (01. 160-170) novel improvements at their front and rear edges with offset branches i1 formed at their opposing ends with eyes and the eyes receive pins 62 positioned in the sleeve 2 3 ends 52 and 54; Spring clips 64 project outwardly from the sleeve ends 54 and include angular companion arms 66 and 68. The arms are formed with apertured vertical sections 10 and laterally projecting ends l2 and 14. The ends I0 are formed on their upper faces with projections or protuberances 'Itregisterable with openings 18 formed in the ends 12. The rear edges of the slats are anchored between the ends of the arms by means of the projections inserted in the slats. The cords 38 and 40 extend through the openings in the section 10 of the arms and the lower ends thereof are tied upon themselves to form stops 80. I In use, the blind is raised and loweredin fashion similar to a conventional window shade by grasping one of the blinds and pullingthe entire blind assembly downwardly; .To tilt the blind, so that the slats are slanted upwardly or downwardly, it is necessary, to rotatethe rod, 45 to which the transverse bars 52 of the upper section 48 are secured, either by remote comm: means attached to the rod or by moving one of the slats.

However, since many other modification'sfand purposes of this invention will become readily apparent to those skilledin the art upon a perusal of the foregoing description it isto be under.- stood that certain changes in style, sizeand components may be effected without a departure from the spirit of the invention and within the scope of the appended claims.

Having described the inventions what is claimed as new is:

1. A Venetian" blind comprising supporting brackets, a spring actuated roller rotatably journaled on said brackets, vertically collapsible and tiltable slats, a collapsible structure supporting said slats including a plurality of vertically spaced, parallel, transverse-bars terminating; in

laterally extending end portions, rigid, vertically extending links spacing said transverse bars and pivotally connected to the end portionsthereof, means on alternate of said transverse bars securing slats thereto, a supporting member journaled on said brackets, vertically collapsible and tiltable slats, a collapsible structure supporting said slats including a plurality of vertically spaced, parallel, transverse bars terminating in laterally extending end portions, rigid, vertically extending links spacing said transverse bars and pivotally connected to the end portions thereof, means on alternate of said transverse bars securing slats thereto, a supporting member mounted on said brackets and tiltingly securing said collapsible structure thereto, means associated with said roller and the lowermost of said transverse bars whereby the lowermost bar may be moved upwardly to efiect the sequential collapsing of said rigid links and consequently decrease the spacing between said bars and slats thus collapsing the slats, said supporting member comprising a rod frictionally and rotatably mounted on said brackets.

3. A Venetian blind comprising supporting brackets, a spring actuated roller rotatably jour naled on said brackets, vertically collapsible and tiltable slats,,a collapsible structure supporting said slats including a plurality of vertically spaced, parallel, transverse bars terminating in laterally extending end portions, rigid, vertically extending links spacing said transverse bars and pivotally connected to the end portions thereof, means on alternate of said transverse bars se curing slats thereto, a supporting member mounted on said brackets and tiltin gly securing said collapsible structure thereto, means associated with said roller and the lowermost of said transverse bars whereby the lowermost car may be'moved upwardly to effect the sequential collapsing of said rigid links and consequently decrease the spacingbetween said bars and slats thus collapsing the slats, said supporting member comprising a rod frictionally and rotatably mounted on said brackets, said rod having aslotted portion receiving the uppermost of said transverse bars whereby upon rotation of the .rod the transverse bars and slats secured thereto will be tilted. V

4. A Venetian blind comprising supporting brackets, a spring actuated roller rotatably jour naled on said brackets, vertically collapsible and tiltable slats, a collapsible structure supporting said slats including a plurality of vertically spaced, parallel, transverse bars terminating in laterally extending end portions, rigid, vertically extending linksspacing said transverse bars and pivotally connected to the end portions thereof,

means on alternate of said transverse bars securing slats thereto, a supporting member mounted on said brackets and tiltingly securing 7 said collapsible structure thereto, means associated with said roller and the lowermost'of said transverse bars whereby the lowermost bar may be moved upwardly to effect the sequential collapsing of said rigid links and consequently decrease the spacing between said bars and slats thus collapsing the slats, said slat securing 'means comprising slat receiving arms rigidly attached to the ends of said bars. 1

5. A Venetian blind having a pair of collapse,

' lapsible sections, each collapsible section includ-- 4 f ible structures supporting the slats in vertically spaced alignment, said collapsible structures each including a plurality of vertically spaced,

parallel, transverse bars terminating in laterally links spacing the bars are pivoted aboutthe ends thereof thus collapsing the structure. 1

6. A Venetian blind comprising supporting brackets, a spring actuated roller rotatably journaled on said brackets, a pair of collapsible structures supporting the slats in vertically spaced alignment, said collapsible structures each including a plurality of vertically spaced, parallel, transverse bars terminating in laterally extending endportions, alternate bars having arms rigidly mounted on one end thereof to which the slats are secured, vertically disposed, parallel links spacing said bars and pivotally connected to the endportions thereof, cords secured to the lowermost transverse bar of each collapsible structure, said cords beingguidingly received by said arms and attached to said roller whereby upon actuation of the roller the cord will be raised consequently pivoting the links about the ends of the transverse bars thus collapsing the barsand slats connected thereto.

7. The combination of claim 6 wherein said slat securing arms each comprises a pair of angularly related armscomplementally slotted for guidingly receiving said cord;

8. A collapsiblestructure for a Venetian blind comprising a plurality of interconnected coling upper and lower transverse bars terminating in laterally extending sleeve ends, vertically extending links terminating in eyelets, pins pivotally interconnecting said eyelets to said sleeve ends, alternate transverse bars having slat re ceiving arms rigidly secured to an end thereof.
